By mistake I once added "Greek yogurt with honey " , instead of "natural yogurt", to my curry. It was delicious and I use it all the time now. Give it a go. You might enjoy it too...
adding sweet things to curry isn't that unusual when you think about it...
Many spicy foods use raisens and I know someone who always added a jar of apple sauce to his curry !
sounds like a great mistake to make !
